Karpenter patterns with Spot

**Is your feature request related to a problem? Please describe.**
Karpenter Addon could have a pattern where Spot instance is utilized.

**Describe the solution you'd like**
Create a new pattern or revise the current Karpenter pattern to illustrate how to use with Spot

**Additional context**
It will need to check for a prerequisite - EC2 Spot Service Linked Role

The issue does not name files, tests, or an entry point. Start by locating the existing Karpenter pattern in this TypeScript repository and checking how patterns declare prerequisites; then investigate the EC2 Spot Service Linked Role requirement. Done means the repository contains a documented Karpenter Spot pattern or a clearly revised existing pattern with the prerequisite handled.
